BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent NO. 437,487, datedSeptember 30, 1890.

Application filed June 13,1890- Serial No. 355,335. (No model.)

To all whom it may concern.-

Be it knownthat we, CHARLES W. FISCHER and ANTON J. ROLLERT, citizens ofthe United States of America, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and usefullmprovementsin Barbers Chairs, of which the following is -a specification, referencebeing had therein to the accompanying drawings.

This our invention has for its object to provide a simple attachment tobarbers chairs, which, besides locking the tilting seat in a horizontalor in reclining positions, will also enable the barber by the pressureof his foot and without the assistance of his hand to lift the seat,with the occupantthereon, from a reclining to a horizontal position; andV with these objects in view our invention consists of the novel devicesand combinations of devices hereinafter described and specificallyclaimed.

In the accompanying drawings, Figure 1 represents a sectional sideelevation of a barbers chair provided with our improvements, the seatbeing in its horizontal position; and Fig. 2 is a similar view with theseat in its reclining position. Fig. 3 isabottom view of theseat-supporting frame and of the seat-opcrating device thereon, and Fig.lis a section on line 4: 4 in Fig. 1.

Corresponding letters of reference in the several figures of thedrawings designate like parts.

A is the base.or seat-supporting frame, and B the seat-frame, both ofthe usual construction and pivotallyconnected at b in the usual manner.

Against the side brace-bars a of seat-frame A are secured boxes 0,between which is fixed a shaft or rod C. Upon the middle of this shaftor rod C is mounted eccentrically a segmental disk D, against the upperend of the forward chord edge of which is pivotally connected, by plates6, the chord edgeof the segmental pawl d. Both the disk D and pawl d aresurrounded bya ring F, having an arm f, the upper eyed end of which ispivotally coupled with a bracket g, rigidly secured under the rear endof the seat-frame B, whereby a rotating movement of disk D will impart atilting movement to the chair-seat.

H is the pedal-lever extending from under the rear-of seat-frame A, andbeingforwardly bifurcated to provide a split hub 72-, that is pivotedupon shaft C, embracing the eccentric disk D. Each such hub part It hasa forwardly-extended radial arm 1', the two arms 1' embracing thesegmental pawl d, and, being eyed at near their ends, the two arms 1'are connected by a pinj, Secured therein and passed through a slot at insegmental pawl d.

This pawl (I, being pivotally coupled'with segmental disk D, asdescribed, its lower portion is free to swing against or out of contactwith the inside face of ring F, and the pawl (1, having teeth formed tothe lower half of its arc, meshing with corresponding teeth formed tothe inner pcripherical surface of the lower one-third of thecircumference of ring F, the slot m in pawl 01 is on a direction angularto the circumferential line of ring F, as well as to the arc movementimparted to pin j of arms 1; of the pedal H, for the purpose that adown-swinging movement of such pin j will swing the pawl cl outwardagainst ring F and the teeth of both the pawl d and ring F intoengagement with each other, and that a slight upward movement of pin jwill swing pawl d so that its teeth will clear the teeth of ring F.Against each side of disk D is fixed a spring n in a manner to presswith its free end upon the end of one of the armst' in a downwarddirection, thereby tending to swing the pawl d outward and to hold theteeth of both the pawl d and ring F in engagement. With a slightdownward pressure upon pedal II the arms 1' will force the springs nelastically to yield for the pin j, moving upward in slot m, to swingthe pawl cl and its teeth out of engagement with ring F, when the disk Dwill be free to turn in ring F. for raising or lowerin g the rear of thechair-seat.

With a slight pressure upon the pedal H, and then following with thefoot the upswinging movement of the pedal, the seat B, with the occupantthereon, can be slowly reclined, and for swinging the chair-seat againto a horizontal position a heavier down-pressure of the foot upon thepedal 11 will not only disengage the teeth of pawl 01 and ring F, butwill also turn the eccentric disk D to lift the rear of the chair-seatwithout the assistance ICO of the hand, and then by removing the footfrom the pedal H the springs n will at once come into operation forlocking the teeth of the pawl with those of the ring rigidly to hold thechair-seat in its acquired position.

It will thus be seen that the whole operation of this chair is easy, andis obtained by Very simple devices not liable to get out of order.

What we claim is 1. In abarbers chair, the combination, with the baseand se'at pivotally connected, of a shaft or rod transversely secured inthe base, an eccentric and a pedal pivoted upon such rod and bothconnected to move simultaneously, and a ring or strap surrounding theeccentric and having an arm coupled with the chair-seat, allsubstantially as set forth.

2. In abarbers chair, the combination, with the base and seat pivotallyconnected, of a shaft. or rod transversely secured in the base, asegmental disk ec'centrically mounted upon the shaft or rod and asegmental pawl pivotally connected with the segmental disk, a ring or.strap surrounding the disk and engaging the pawl and having an armconnecting with .the end of the seat, and the pedal pivoted upon the rodor shaft, with arms connecting with the pawl for disengaging the samefrom the ring and for turning the disk, all substantially as set forth.7

3.. In abarbers chair, thecombination,with the base and seat pivotallyconnected, of shaft or rod 0, within the base of segmental eccentric D,mounted upon shaft or rod C, ring or strap F, surrounding eccentric Dand having arm f coupled with the chair-seat, pedal-lever H, pivotedupon shaft or rod 0 and coupled with a pawl d, again coupled Witheccentric D, and engaging teeth of ring or strap F for locking the partsto be rigid, the whole being arranged so that a depression of the pedalwill first disengage the pawl d from the strap and will then rotate orfollow the movement of the eccentric D, all substantially as set forth.

4. In a barbers chair, the combination, with the base and seat pivotallyconnected, of shaft or rod 0, segmental eccentric D, mounted upon shaft0, segmental pawl 01, pivotally connected with eccentric D and havingangular slot m, ring or strap F, with arm f, coupled with thechair-seat, pedal-lever H, pivoted upon shaft or rod 0 and having arms 1with pin j, engaging slot m, and springs n, secured to eccentric'D andpressing upon arms 2', all substantially as set forth, to operate asspecified.

In testimony whereof we affix our signatures in presence of twowitnesses.
